Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Did you perform these steps AFTER inserting the device, like requested?

The command, tail, displays the last entries in a log file. In this particular case, you were getting the last entries in the messages log that is contained in your /var/log directory. The objective was to see if you get any sort of response from your system indicating that it saw activity when you inserted the USB device. If you inserted a device and then performed the command, it suggests that your system did not 'see' that a device had been inserted. This being the case, I would suggest that you can see if your system recognizes that it has a USB controller and whether or not it has any USB drivers (aka modules) loaded into the kernel. You may have a compatibility issue or even a hardware failure.

You can do this with two commands. First:

Code:

sudo lspci | grep -i usb

This command runs lspci, which lists the devices that are seen on your PCI bus and filters for anything containing the word USB.
Second:

Code:

sudo lsmod | grep -i usb

This command does a similar function, but lists the kernel modules, i.e. drivers, that are installed in your system.

This tells me that I have two USB controllers, each of which has an open host controller and an extended host controller and that I am using the modules usbhid and hid (which is in turn used by usbhid).

thanks, I can see how that works. I tried the USB and had no response. my first instruction
was to do the 'tail' first, then put in a CD, I then got this error code. I'll try what you
said next, to see what results I get .

After pasting message in window highligh the pasted content only, at the top of quick reply box there is a row of icons, if you put mouse on them they'll say what they are.
You want the 1 that says "wrap quote tags arouund selected text". Later on you can experiment in Advanced section under "Go Advanced" button.

I guess I can't be helped. but, I think you guys are great, and I really do appreciate you
trying. I was hoping it would be some simple, 'little' thing. and I'd have a fighting chance.
but, I'll keep trying, somehow, somewhere I'll 'find it'.
thanks again, and have fun.
